The invention provides a flexible polyether-ether-ketone thermal control film, a preparation method and application. The thermal control film comprises a base material and a reflecting layer on the surface of the base material, wherein the base material is a colorless and transparent polyether-ether-ketone blending alloy film, the reflecting layer is a silver layer or an aluminum layer, the thermal decomposition temperature of the polyether-ether-ketone blending alloy film is not lower than 500 DEG C, and the glass transition temperature is not lower than 150 DEG C. According to the invention, the flexible polyether-ether-ketone thermal control film can be pasted on the surface position of a spacecraft such as a satellite and the like, so that the thermal control performance of the spacecraft is improved, and the problem that the service life of a product is affected by film splicing is effectively solved; the thermal control film is made of a flexible material, can effectively solve the problems that a tradi
